FISHING-TOOL.

SPECIFICATION forming part of Letters Patent No. 769,140, dated August30, 1904. Application led November S, 1903. Serial No. 183,099. (Nomodel.)

To a/ZZ whom, it may con/cern:

Be it known that I, CHARLES M. IIEETER, of Butler, Butler county,Pennsylvania, ,have invented `a new and useful Fishing-Tool, of

which the following is a full, clear, and exact; I description,reference being had to the accom.`

panying drawings, forming part of this'speciiication, 1n which- Figure 1shows in elevation my fishing-toolwhenin use in removing a detached bitor tool from an oil-well.

Fig. 3 is a separate view of the fishing-tool, and Fig. A is a detailview showing the fishing-tool engaged with a diferent portion of thedetached bit from that illustrated in Figs. 1 and 2.

The difficulties whichhave heretofore atftended the removal of detachedtools or bits from oil-wells have been the occasion of great expense andloss to yoil-well drillers and operators; and it is the'purpose of myinvention to provide means for this purpose which shall be reliable inits actionl and which will enablethe removal of bits or tools from wellsmore certainly and quickly than has been possible heretofore.

My invention consists in a 'lishing-tool of new construction; and italso consistsin a drilling-tool having a lateral recess affording ashoulder for engagement by my fishingetool or by fishing-tools fof otherconstruction.

Inthe accompanying drawings, Fig. il, 2 represents a bit ordrilling-tool which has been broken off and lodged in an oil-well.having been crowded against and into the soft rock at the side of thewell in a manner which prevents its engagement by fishing-tools or' thekind ordinarily employed. i 3 is the fishing-tool which I Aemploy forremoving such'.

bit." This tool consists of a head portion or socket A, by which it isconnected to the stem or string of tools 5, 'extending to the top of thewell. fishing-tool is reduced in thickness and extends downwardly fromone side of the head portion, so that it may be inserted along the sideof the bit or tool to be removed, and it is provided with a hook 6,v theextremity or' Fig. 2 is asimilar view seen at right angles to Fig. l.

The lower portion or shank of the 'which is preferably made of hardenedsteel, so as to insure its engagement with the tool to be removed.

lfrom the fishing-tool preferably below the vhook 6` and when theiishing-tool enters between the bit 2 and the wall of the well isadapted to bear against the wall of the well and to exert upon thefishing-tool a pressure tending to push it toward the bit.

In the use of my fishing-tool it is lowered into the well until itpasses between the side it comes opposite to anjupwardly-recessedportion B, which I form for that purpose on the bit or drilling-tool, itis forced inwardly by the spring 7 and when it is next drawn up the hook6 will engage the recess B and the bit 2 can be drawn with thelishingtool to the top of the well. i

I prefer to for'rnvon the bit 2 one of the recesses B or B on each sideof the bit 2. so that the fishing-tool will engage with the bit at tweenthe bit and the wall. The fishing-tool, however, may be used to removetools or bits which are not provided with recesses B or B'. In this caseif the hook 6 be made of hardened steel the spring 7 will cause it tobite upon well and to dislodge `it from the sides .suie ciently toenable a horn-socket, (which is a common jrisl1in ,rtool,) to beinserted into the well and engage with it, whereas without thepreliminary dislodging of the bit it is often difHcult and sometimesimpossible to cause the Vhorn-socket to` engage it.

Within the scope of my invention as delined in the claimsthe apparatusmay be modified in construction in various ways, since What' I claimisl. A fishing-tool for deep wells havinga hook adapted to be insertedinto the space between one side of a lodged tool and the side of thewell, and a spring guide or arm adapted to press the hook toward thelodged tool; substantially as described.
